Matthias Braun da5e7e11d1 SelectionDAGBuilder, mach-o: Skip trap after noreturn call (for Mach-O) ...

Add NoTrapAfterNoreturn target option which skips emission of traps
behind noreturn calls even if TrapUnreachable is enabled.

Enable the feature on Mach-O to save code size; Comments suggest it is
not possible to enable it for the other users of TrapUnreachable.
